I have hats ranging from 73/8 to 7 3/4 in my trunk and they all fit the same. I can try on multiple hats in the same year with the same size shown on the tag from the same mfg at the same clinic and have one that fits, one that's too big and one that's too small.
In cases where the batting helmet is accidentally hit with a batted ball on or over fair territory or a thrown ball, the ball remains in play the same as if it has not hit the helmet.
If a batted ball strikes a batting helmet or any other object foreign to the natural ground while on foul territory, it is a foul ball and the ball is dead.
If, in the umpire’s judgment, there is intent on the part of a baserunner to interfere with a batted or thrown ball by dropping the helmet or throwing it at the ball, then the runner would be out, the ball dead and runners would return to last base legally touched.
I'm not accusing Thunderheads of this, but there are certainly posters who would take the exact same pitch if it happened to (insert name of your favourite douchebag player here) and wonder why PU didn't eject him immediately.
Do "they" adjust this chart based on the height of the batter? I'm glad to see the high strike called (well, when it is a strike). Makes it easier to call it at the levels I do. One of the talking heads said something to the effect that Cabrera was upset about a pitch earlier in the at-bat (I think). The chart shows that he has nothing there to be upset about.
